CURING DEVICE.

Application filed April- 20, 1925. Serial No. 24,579.

This invention relates to a new and improved coring device ofthe type used for coring and seeding grapefruit and other fruit. I

Among other aims and objects of the invention may be recited the provision of a device of the character mentioned,.with a View to compactness, in which the number of parts are few, the construction simple,- the cost of production small but efliciency of operation high.. I a

The improvements in details and arrangement of parts will be apparent from an inspection'of the accompanying drawings, in connection with the description hereinafter contained, wherein a preferred embodiment ofthe invention is. disclosed for the purpose of imparting an understanding of the same.

the several views; a

. well known in the art.

Figure 1 is a side elevation of my new and improved coring device with the members in their closed positions;

'Figure 2 is an, end elevation thereof;

Figure 3 is a plan viewthereof; Figure 4 is a fragmentary side elevation thereof with the members in their open positions;

Figure 5-is a side elevation of the device positionedfor cutting a core of smaller size than as shownin'Figurel; and

Figurefi is a plan view of a blank before it is bent into its completed form.

My improved coring device is constructed essentially of two parts, each preferably made of a single piece of metal and pivotally connected with each other.

In this device I eliminate the requirement of a tubular cutter andthe devices connected therewith, whereby pressure may beapplied thereto in accordance with a structure now Referring to the drawings, each of the two members 10 and 11 is preferably constructed from a singlefiaiece of sheet metal, and respectively provided with arm portions 12 and 13, which are joined at their lower ends by the semi-circular cutter portions 14 and 15. The upper free ends of the arms are joined by the rods 16 and the arms 13 are oined by an additional rod 17 These cutters 14 and 15 are preferably of such height and curvature that they will form a bowl when adjacent to each other,

as shown in Figure 4. The studs 18 provide convenient means for pivotally connectin the members 10 and 11 together.

The lower edges of the arms 13 are each provided with a stop shoulder 19, which project over and contact with the upper edge 20 of the semi-circular cutter 14 when the members 10 and ll are in their closed position, substantially as shown in Figure 1. By this engagement of the parts the cutters 14 and 15 are held in position where they combine to form substantially a complete circle and inthis'p0siti0n they are forced downwardly into the fruit around the core thereof, which is severed thereby. When the same has been pressed into the fruit a suflicient distance, the arms12 and 13 are moved upon their pivot mounting until they occupy a position relative to each other, substantially as shown in Figure 4. During this movement the cutters 14 and 15 move in a circular path around the studs 18 and the cutting edges 21 thereof pass under and se arate the corefrom the fruit upon its nn erside. a

In Figure 4 the adjacent edges 21 of the cutters 14 and 15 are indicated as being slightly separated. The relative positions of the cutters 14 and 15 are'usually' sufficient to separate the core from the fruit but as the cutter 15 is slightly smaller than the the arms WhlCh results in such relative positioning of the cutter portions 14 and 15 that they will cut a core much smaller than when the cutters are as arranged in Figure 1. Thus the device is not limited to successive cuttings of the same size but is ada ted to cuttings of varying sizes as desire What I claim as new and desire to secure by Letters Patent, is:

1. A coring device including a pair of substantially similar members each having a air of arms and a substantially semi- 'sp erical shell-like cutter connecting the arms, said cutters being of relatively con- In Figure 5 the device is illustrated with 12 and 13 partially separated, v

sidei'able width to conjointly form a bowl of substantial size when'the cutting edges lie adjacent to each other so as to enable complete removal of the core by the bowl alone, and means to pivotally connect the cutters.

2. A coring device including a pair of substantially similar members each having a. pair of arms and a substantially semispherical shell-like cutter connecting the arms, said cutters being of relatively considerable width to conjointly form a bowl of substantial size when the cutting edges lie adjacent to each other so as to enable complete removal of the core by the bowl alone, a shoulder on one member formed to engage the upper edge of the adjacent cutter so as t-ffhold the cutting edges in substantially a common plane, and means to pivotelly connect the cutters.

3. A coring device including a pair .of substantially similar members each having a pair of operating arms, a substantially semi-spherical shell-like cutter connected at its free ends to the lower ends of the respective arms, means pivotally connecting the free ends of the pair of cutters, handles carried by the upper ends of the arms and being aligned with the closed ends of their respective cutters,'and a stop formed on one of said arms adjacent the lower end thereof adapted to engage the upper edge of the cutter carried by the opposite arms to hold the cutting edges in substantially a common plane when said cutters are in open position.

In testimony whereof, I have hereunto affixed my signature.
